The purpose of the research was to study the frequency of erythrocyte antigens of 9 genetic systems, the number of genotypes and the frequency of alleles in the F-V system in sires Simmental and Red-and-White breeds, as well as to establish the index of genetic similarity between them.The characteristics of 106 sires Simmental and 103 Red-and-White breeds in OJSC “Barnaulskoe” Stud bull farm have been given according to the frequency of erythrocyte antigens of 9 genetic systems. 53 antiserums have been used in the tests. The high occurrence of erythrocyte antigens A2 (system A), B2, G2, O1, Y2, G’, O’, and Q’ (system B), C2, E, W, X2 (system C), S1, H’ (system S), and Z (system Z) has been found in the sires of both breeds and ranged from 0,204 (O’) to 0,825 (X2) in Red-and-White bulls. The maximum frequency of the F antigen was and it was 0,874 in Red-and-White and 0,906 in Simmental bulls. On the contrary, the occurrence of blood factors B1, I1, I2, O2, P1, P2, Q, T1, T2, I’, D’, J2’, K’, P1’, P2’, Y’, B”, G”, R1, J, H, U and U’ was signifi cantly lower and amounted to 0–0,107 in Red-and-White sires and 0–0,094 in Simmental sires. Only 42 erythrocyte antigens have been detected in Red-and-White bulls using 53 antiserums, and 44 antigens have been detected in Simmental bulls. The index of genetic similarity between Red-and-White and Simmental sires calculated according to A. S. Serebrovsky was quite high and amounted to 0,8765, which is understandable because the maternal breed when breeding Red-and-White breed was Simmental breed. The number of genotypes and the frequency of alleles in the F-V genetic system also revealed a great similarity between these breeds, a significant difference has been found only in the number of heterozygous animals.

The paper characterizes 52 producers of red steppe, 49 - red Danish and 169 Angler bulls of “Barnaulskoye” enterprise in terms of erythrocyte antigen occurrence. The authors used 53 antiserums in order to determine erythrocytic antigens of 9 genetic systems. The highest frequency observed was F antigen frequency equal to 0.976-1.000. This gene was not observed in one servicing red steppe bull and four servicing Angler bulls. All red Danish bulls had F allele in a homo- or heterozygous state. The concentration of antigens A2, B2, O1, Y2, G’, Q’ (system B), C1, C2, E, R2, W, X2 (system C), H’ (system S) in the red bulls was high and equal to 0.249-0.592. The frequency of erythrocytic antigens B1, I1, P2, T1, T2, Y1, I’, D’, J2’, P1’, B” (B), R1 (C), J (J), S2, U and H” (S) was the lowest at 0-0.122. All 53 blood factors were observed in Angler cattle, but no antigens B1, P2, R1, U и B1, Y1, B” were observed in the red steppe and red Danish cattle. There are no significant differences observed in genetic similarity among three red breeds; the index of genetic similarity are 0.9211-0.9307, which indicates a high relationship among them. The highest number of ejaculates and native sperm was obtained from Angler servicing bulls, the excess over other breeds was 11.9-13.9 and 15.1-42.8%. Red steppe bulls were characterized by lowest amount of ejaculate and less bioproducts for cryopreservation were received from them. The total breeding efficiency of cows with red steppe bull sperm was 85.1%, the superiority over Danish and Angler red cattle was 7.1-11.5%.

Purpose: to study hematological parameters of blood in bulls-producers of dairy breeds on the day of semen collection in the Udmurt Republic after a long winter period of operation, depending on the breeds, age and place of selection.Materials and methods. The work was performed at the Federal Research Center for Animal Husbandry named after Academy Member L. K. Ernst on the basis of AO "Udmurtplem" of the Udmurt Republic in the period from 2020 to 2021 on dairy bulls (n=20) aged 15-69 months, including a purebred Holstein breed of domestic selection (n=6), a Holstein black-and-white breed of European selection (the Netherlands, n=6), a black-and-white breed with blood transfusion on Holsteins on at the level of 94-98% (n=8). The content of white blood cells, red blood cells, hemoglobin and hematocrit, depending on age and breed, was studied on the ABC VET hematological analyzer on the day of taking the seed.Results. It was found that on average, in 20 bulls aged 15-69 months, the level of white blood cells was at the level of reference values of 8.8±0.25 x 109/l, red blood cells 10.3 x 1012/l, which is 50% more than the reference values. The concentration of hemoglobin is 128.0±2.92 g/l, hematocrit is on average 54.3%, with a norm of 24-46%. Breeding bulls at a reliable level, differing in age, showed that some animals had high indicators for red blood cells of 10.3±0.26 x 102, for hematocrit of 54.3% against 24-46% of reference values. Also, according to hematological indicators, there was a tendency to increase the concentration of hemoglobin and hematocrit in European-bred bulls.Conclusion. The study of the variability in hematological parameters depending on the selection showed that there is no significant difference in leukocytes and all indicators are at the level of reference values, and in erythrocytes more than 50% than the highest indicators. The highest hemoglobin values were at the level of 141-156 g/l instead of 128 g/l according to the highest reference values. Hematocrit also showed high max values in all groups in comparison with the reference values of 59-66% versus 46% in the norm. It is necessary when analyzing hematological blood parameters in addition to the average statistical indicators (M+m) also, monitor the variability (min-max) in order to obtain more objective information.

Improving of fertility indicators and reproductive qualities of sows during artificial insemination in farms of different specializations is very topical issue. The introduction of artificial insemination of sows on breeding farms by the spermdoses of optimum volume, by the frozen-thawed and sex sperm requires the introduction of innovative reproductive technologies. The use of economical methods of artificial insemination of sows using a minimum number of sperm in a small volume of spermdose in order to achieve high rates of fertility and prolificacy was proven in numerous experiments of the authors. Significantly reduced spermdose may be sufficient if the sperm enters deep enough into the uterus. Vitality of sperm does not depend on the size of spermdose, but the best place for sperm to survive one oviducts where they keep the fertilizing capacity from 9 to 27 hours. So deep intrauterine insemination of sows improves conditions for sperm survival The aim was to study the feasibility and justification for widespread implementation in to production on breeding farms of intrauterine insemination of sows morder to increase their fertilization and prolificacy and  to save the boar sperm with the highest index of breeding values. Experiments were conducted in terms of selection and genetic center of Agrofirm "Mig-Service-Agro" in Mykolaiv region. In the experiment used 65 sows of live weight of 280-320 kg wiht 2-4 farrowing were. Sows in sexual hunting were showed once daily in the morning using a boar-prober. Artificial insemination was performed twice: the first time - in the afternoon and at 14-16 p.m. The second time – in the morning of the next day at 9-10 am. For artificial insemination of sows were ed using experimental spermodes with volume of 40 ml which contained 1.5 billion of a Active sperm. For the dilution of sperm was used Durasperm - KRUUSE (Denmark) the period of sperm perpetuation is 5-7 days. To enter the were semen used catheters Magaplus S, (Spain) for intrauterine insemination of sows. Analysis shows that the period from weaning to insemination has significant difference comparing sows of large White breed with Landrace breed (p <0.001), with genotype sows F1 (p <0.01) and sows of the Duroc breed (p <0.05). For all selected 65 sows duration of suckling period, was estimated which averaged 32.2 days and the average time from weaning of pigs to their sexual inclination and the first intrauterine insemination 6.8 days that meets the physiological norm. After intrauterine insemination of sows of then 48 farrowed, which wich made for 73.9%. іncluding live 5 emergency farrow  were obtained, representing 10.4% of all amount. Percentage of farrow is considered physiologically normal – 80%, or more of total insemined sows. The very low percentage of farrow 53.3% had of sows F1, and the highest percentage was found by sows of the Duroc breed – 85.7%. Pregnency of sows were received just 17, which made 26.1% and highest percentage – 46.7% was set by sows F1. Analysis of the pregnancy sows shows that on average it is 116.2 days was the longest – 117.1 days was set in Landrace breed sows and the short est 115.5 days in Large White breed, but the difference is not significant. 571 pigs were received, іncluding live 451 head, which is 78.9%. The largest percentage of іncluding live piglets obtained from sows F1 – 82.5%, and the lowest in Landrace breeds – 77.0% and Large White – 77.3%. Exit of all piglets per sow without emergency farrowings is 12.2, іncluding live – 9,8. The highest yield were obtained piglets from sows F1 – 13.1, іncluding live – 10.9, the lowest yield of sows of the Duroc breed – 10.6, іncluding live 9.1, which has significant difference compared with the control (IDPs) and other breeds.  After intrauterine insemination 8 sows showed cyclic deregulation in 20-25 days, ie repeated sexual hunt took place on average 22.3 days. These sows were inseminated by not fractional way, they farrowed and an average litter just 13.1 piglets per sow, іncluding live - 11.3 was obtained. Repeating after intrauterine insemination on 45-48-49 day in the sexual hunt came about three sows for artificial insemination by not fractional method 3 farrowed and was obtained output – 13.3 piglets, іncluding live – 11.7. It should be noted that the best sow Large White breed №12 after intrauterine insemination bore 16 pigs, іncluding live 11, sow of Landrace breed №1556 – 18 pigs, іncluding live 12, Duroc №5888 – 13 pigs, іncluding live 11, sow F1 №167 – 20 pigs, іncluding live 14 pigs. Breeding requires more careful handling with major sows taking into account their breeding value and cost, that’s why we believe that there is no need to risk causing injury genitals with intrauterine insemination if a sufficient number of spermdoses of boars-sires exist.

Hydroxyapatite (HA) is a bioceramic with excellentbiocompatible properties, and composition and crystal structure similar to apatite in the human dental structure and skeletal system. A number of researchers have attempted to evaluate the effect of the addition of HA powders to increasemechanical properties of restorative dental materials. In this study, HA was synthesized using chicken eggshell as calcium source for synthesizing HA by using precipitation technique. The aim of this study was to determine the effect of incorporation of eggshell-derived HA on the surface  hardness GIC (Fuji IX GP). Specimens were divided into two groups: group GIC without incorporation of HA as control group (n = 16) and group GIC with incorporation of 5% HA as experimental group (n = 16). Total of specimens were 32 cylinders 5mm diameter and 2mm height. Surface hardness GIC was measured with vickers microhardness tester. Data wasanalyzed by unpaired T-test. The mean of surface hardness for GIC control group was 51.37 ± 1,63VHN and the experimental group was 56.60 ± 1,22HVN. The results T-test showed a significant difference between groups (p<0.05). It can be concluded thatincorporation of eggshell-derivedHA could increasesurface hardness of GIC.

Abstract Objective: To test the null hypothesis that there is no significant difference between the microleakage of adhesive interferences at the occlusal and gingival margins of both ceramic and metallic brackets bonded with light-cured resin-modified glass ionomer and a conventional adhesive. Materials and Methods: Sixty freshly extracted human maxillary premolar teeth were randomly divided into four groups of 15 teeth each. Metal and ceramic brackets were bonded to groups 1 and 2 with resin-modified glass ionomer adhesive (RMGIA). Metal and ceramic brackets were bonded to group 3 and group 4 with a conventional adhesive (CA) system. A dye-penetration method was used for microleakage evaluation. Microleakage from the occlusal and gingival margins was determined by a stereomicroscope for the enamel-adhesive and bracket-adhesive interfaces. Statistical analysis was performed using the Kruskal-Wallis test and the Mann-Whitney U-test with a Bonferroni correction. Results: The gingival side of all groups exhibited higher microleakage scores compared with the occlusal side for both adhesive interfaces. All bracket and adhesive combinations displayed statistically significant differences in microleakage between the enamel-adhesive and adhesive-bracket interfaces at the occlusal and gingival sides of the brackets (P &lt; .001). When the adhesive systems were compared, the RMGIA showed more microleakage than the CA between the different interfaces. Conclusions: The hypothesis is rejected. RMGIA results in more microleakage between enamel-adhesive interfaces.

Abstract Background Patient handoffs are ubiquitous in hospital settings. Historically, formal handoffs of patient information have been conducted in the inpatient setting mainly by primary teams, as opposed to medical and surgical consultants. Carelign is a software developed by the University of Pennsylvania Health System to function as an interdisciplinary, patient-centered handoff. While mainly utilized by primary teams for work management and transitions, it has been enhanced to include specialty consultant handoff functionality. Objective The aim of this study is to determine whether using Carelign for consultant handoffs improves clinical handoffs in comparison to the prior handoff system (a custom-built handoff report within the electronic health record) used by the Department of Ophthalmology at Penn Presbyterian Medical Center. Methods A 7-item questionnaire assessing the effectiveness, efficiency, accessibility, reliability, communication, and security of the handoff using a 1 to 5 scale was distributed to residents prior to and 6 months subsequent to the implementation of Carelign. Results Users reported a statistically significant increase in Health Insurance Portability and Accountability Act (HIPPA)-compliance (44 vs. 100%, p < 0.0001) and ability to communicate with primary teams (38 vs. 70%, p = 0.019) after implementation of Carelign. There was a trend toward significance with ease of accessing information after switching to Carelign (67 vs. 85%, p = 0.185). There was no statistically significant difference in effectiveness, efficiency, accessibility from home, or reliability of information on handoff after converting to the new system. Conclusion Carelign is perceived to be an effective tool that can be used by consulting providers to ensure HIPPA-compliance and the ability to communicate with primary teams without sacrificing effectiveness, efficiency, accessibility, or reliability.

In order to improve the digestibility and absorption of feed, metabolic processes, growth and development of animals, increase the resistance of the body immunomodulatory agents, probiotics, prebiotics, combined enzyme-probiotic feed additives are widely used. The purpose of our work was to conduct comparative clinical trials of the effectiveness of the probiotic feed additive Probion-forte in terms of productivity, blood indices and histological structure of individual internal  pigs organs during fattening. The researches were carried out on 120 piglets of big white breed at the age of 28 days, which were divided into 4 groups with 30 units in each one. The probiotics were added to feed in different concentrations in order to determine their efficiency and examine influence on piglets organism: the first group was given probiotic Probion-forte in dose of 1.0 g/kg (10 weeks); the second one – Probion in dose of 1.0 g/kg (6 weeks) and 0.5 g/kg (4 weeks); the third one was given probiotic Bio Plus 2B in dose of 0.4 g/kg for 10 weeks; and the fourth one was a control group. The compound feed was provided according to norms recommended for big white breed taking into account age. On the 42nd day (6 weeks) and on the 70th day of test 10 units were selected for haematological, pathomorphological and microbiological tests. The productivity of animals of all studied groups was evaluated by the average daily gains, safety, feed conversion and slaughter output. The stabilized with EDTA piglets’ blood was used for morphological studies, and blood serum – for biochemical studies. The clinical trials have shown that the application of Probion-forte, as a feed additive for fattening of piglets within 10 weeks after weaning, did not cause adverse reactions, was well tolerated by animals and contributed to the improvement of the processes of erythropoiesis and leucopoiesis, increased of serum total protein content. The increasing activity of serum transaminases indicated more intense metabolic processes in experimental animals’ organism, which was confirmed by increase in average daily weight gains and slaughter output compared to control. In the microscopic examination of the thymus, spleen, lymph nodes, intestines, liver, the characteristic histological structure of the organs was preserved and indicated their active morphofunctional state throughout the study period. Morphometrically the increase in the height of the villi in the duodenum and the size of the thymus lobes in piglets, which were fed with probiotic feed additives was established. The efficiency and appropriateness of the application of these products was confirmed in the first and second experimental groups. However, the most significant difference was observed in piglets fed with Probion-forte for 10 weeks at a dose of 1.0 g/kg of feed.

Abstract. Title of the paper: Milk ingestion and growth performance of suckler calves born during winter stalling from German Red and White breed and from old type German Black and White breed in a cow-calf operation On 14 calves from German Red and White breed and on 17 calves from old type German Black and White breed in a cow-calf operation measurements of body weight were done repeatedly during growth after separating the calves from the dams for 150 min and than again after the calves had contacted the dams for 60 min. Measurements took place always at the same daytime. Milk ingestion of calves was assessed by way of body weight difference method. Acute body weight difference varied markedly between calves and increased with age. The fraction of positive weight difference of all measurements was between 60 % and 86,2 % (male 60 % and 86,2 %; female 67,6 % and 80,6 %) in DRB breed and between 69,1 % and 89,3 % (male 72,9 % and 89,3 %; female 69,1 % and 82,6 %) in DSB breed. Means of all measurements showed a significant difference of acute positive body weight change and of growth rate between breeds and sexes. Mean acute positive body weight changes developed with life age and body growth with different degree in male and female calves. Growth rate of calves showed greater inter- and intraindividual variation from 1 to 10 days of life age. Differences in growth rate between male and female calves were more profound in DRB breed than in DSB breed.

The Ceratozamia norstogii complex from Southern Mexico is made up of four closely related taxa and occurs in similar habitats (Quercus forest). All have linear-lanceolate leaflets with great similarity between them, especially in juvenile stages, but differentiate with age. There has been debate regarding delimitation of species due to character loss in herbarium specimens. The aim of this study was to determine the genetic variation, and to measure genetic similarity between the four taxa. We studied populations in Cintalapa (Chiapas) for C. alvarezii and C. norstogii; the Sierra Atravesada (Oaxaca) for C. chimalapensis, and Villa Flores (Chiapas) for C. mirandae. One population for each taxon was sampled (only one population is known for C. alvarezii) 11-15 randomly chosen adult individuals were sampled. Twenty-eight primers were tested of which five were polymorphic using the RAPD’S technique. The data were analyzed using Bayesian methods. Results revealed low genetic diversity, and a differentiation was found between species, suggesting a recent divergence. A previous morphological and anatomical study on the complex has found the taxa to be distinct. However, the results of this study have shown that the C. norstogii species complex is in a divergence process, probably through genetic drift and founder effects.
